Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a method and device for controlling a train door system during an on-site return operation. Background Art

[0002] In the field of urban rail transit, on-site reversal operations play a vital role. On-site reversal means that after the train arrives at the terminal, it does not need to enter the dedicated reversal line or garage, but immediately departs in the opposite direction after completing the boarding and alighting operations of passengers on the same platform. This method greatly shortens the reversal time of the train, thereby improving the overall transportation efficiency of the line. In this process, the control of the door system becomes a key link; if the door system is not controlled in a timely or improper manner, it may directly affect the overall transportation efficiency.

[0003] The door system includes platform doors (also called screen doors) and train doors. The current door system control method is that after completing the original return operation, the on-board equipment automatically calls the wireless network to send a door control command so that the station controls the opening and closing of the platform doors, and is also responsible for automatically controlling the opening and closing of the train doors to complete the coordination of the entire door system.

[0004] However, in the existing methods, there are situations where the wireless network call is successful, the call fails, and the call is held. A successful wireless network call means that the platform door can be closed or opened smoothly; while a failed call will cause the platform door to fail to open and close normally. During the call hold period, the wireless network continues to try to connect, and the driver cannot perform the next door control action during this process. This is easy to cause passengers to be stranded or delayed departure when the driving interval is tight, which in turn affects the efficiency of railway transportation and the travel experience of passengers. Summary of the invention

[0005] In view of the above problems, the present invention provides a train door system control method and device during on-site return operations. The main purpose is to solve the problem that the current door system control method cannot interrupt the call holding state, resulting in passenger detention or delayed departure, thereby affecting the efficiency of railway transportation and the travel experience of passengers.

[0006] In order to solve the above technical problems, the present invention proposes the following solutions:

[0007] In a first aspect, the present invention provides a method for controlling a train door system during an on-site return operation, the method comprising:

[0008] Obtaining call information when the vehicle-mounted device calls the wireless network device;

[0009] When the vehicle-mounted device is in a call holding stage, judging whether a condition for interrupting the call holding is met according to the call information;

[0010] If the conditions are met, an instruction to interrupt the current call hold is sent to the human-machine interface unit, so that after receiving the instruction to interrupt the current call hold, the human-machine interface unit requests the vehicle-mounted device to interrupt the current call hold state;

[0011] After the current call holding state is interrupted, the door system of the train is controlled again using the specified control method.

[0012] In a second aspect, the present invention provides a train door system control device for an in-situ return operation, the device comprising:

[0013] An information acquisition unit, used to acquire call information when the vehicle-mounted device calls the wireless network device;

[0014] A condition judgment unit, used to judge whether a condition for interrupting the call hold is met according to the call information acquired by the information acquisition unit when the vehicle-mounted device is in the call hold stage;

[0015] An instruction sending unit, configured to send an instruction to interrupt the current call holding to the human-machine interface unit if the judgment result of the condition judgment unit is satisfied, so that the human-machine interface unit requests the vehicle-mounted device to interrupt the current call holding state after receiving the instruction to interrupt the current call holding;

[0016] The control unit is used to re-control the door system of the train using a specified control method after the current call holding state is interrupted by the instruction sending unit.

[0017] In order to achieve the above-mentioned purpose, according to the third aspect of the present invention, a storage medium is provided, wherein the storage medium includes a stored program, wherein when the program is running, the device where the storage medium is located is controlled to perform the train door system control method during the on-site return operation of the above-mentioned first aspect.

[0018] In order to achieve the above-mentioned object, according to a fourth aspect of the present invention, a processor is provided, wherein the processor is used to run a program, wherein when the program is running, the train door system control method during the on-site return operation of the above-mentioned first aspect is executed.

[0019] By means of the above technical scheme, the present invention provides a method and device for controlling a train door system during an on-site return operation. When the on-board device is in the call holding stage, the call holding state can be actively interrupted to prevent passengers from being stranded or delayed in departure due to long-term call holding when the train operation interval is close. This can effectively avoid the adverse impact on railway transportation efficiency and ensure that the travel experience of passengers is not damaged. Specifically: First, the call information when the on-board device calls the wireless network device is obtained. Then, it is determined whether the condition for interrupting the call holding is met according to the call information. Once the condition is met, an instruction to interrupt the current call holding will be issued to the human-machine interface unit. After receiving the instruction, the human-machine interface unit will issue a request to the on-board device to interrupt the current call holding state. Once the call holding state is interrupted, the specified control method will be used to re-operate the train door system. In this way, there is no need to wait for the call holding state, and the control of the train door system can be quickly restored, which helps to improve the overall operating efficiency and the travel experience of passengers.

[0026] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0027] In the existing train door system control process, once the system enters the call holding state, the wireless network will continuously try to reestablish the connection within a certain period of time. During this period, the driver cannot perform door control related operations. Especially when the train running interval is tight, this situation may cause passengers to wait longer or the departure is delayed, which not only weakens the efficiency of railway transportation, but also damages the travel experience of passengers. To solve this problem, the inventor has proposed a train door system control method during the original return operation after in-depth research and innovative work. The method breaks the current call holding state by sending an instruction to interrupt the call holding. Doing so can not only restore the control of the train door system, but also avoid causing passengers to be stranded or the departure is delayed when the train running interval is tight, thereby improving the efficiency of railway transportation and improving the travel experience of passengers. However, to achieve the sending of this instruction, specific conditions need to be met, which can be determined by analyzing the call information when the on-board device calls the wireless network device.

[0028] It is worth noting that the train door system control method for on-site reversal operation of the present invention can be implemented by an independent third-party control system. The control system has the ability to communicate with the human-machine interface unit, thereby realizing the door system control method for on-site reversal operation of the train provided by the present invention.

[0029] Next, you can Figure 1 A train door system control method for an on-site return operation provided by an embodiment of the present invention is described. The specific execution steps are as follows: Figure 1 As shown, including:

[0030] 101. Obtain call information when the vehicle-mounted device calls the wireless network device.

[0031] In the embodiment of the present invention, a dual-channel connection is adopted between the human-machine interface device and the vehicle-mounted device to ensure the reliability and redundancy of communication; the vehicle-mounted device and the wireless network device are connected via a wireless channel through a wireless communication antenna.

[0032] When the train completes the original turnaround, the human-machine interface unit device at the other end will start up and register. After the power-on registration is successful, the on-board device will call the wireless network device to initiate a network connection. After receiving the connection request, the wireless network device will try to establish wireless communication with the on-board device. If the wireless communication is successfully established, a message of successful wireless connection will be fed back to the on-board device; otherwise, a message of failed wireless connection will be fed back to the on-board device. If the call is in the hold stage at this time, the human-machine interface unit of the human-machine interface device will display that the on-board device is in the hold state.

[0033] At this time, the third-party control system can obtain the information displayed on the human-machine interface unit that the vehicle-mounted device is in a call holding state by communicating with the human-machine interface device (human-machine interface unit), and thereby obtain the call information when the vehicle-mounted device calls the wireless network device.

[0034] 102. When the vehicle-mounted device is in a call holding stage, determine whether a condition for interrupting the call holding is met according to the call information.

[0035] 103. If the conditions are met, an instruction for terminating the current call hold is sent to the human-machine interface unit, so that after receiving the instruction for terminating the current call hold, the human-machine interface unit requests the vehicle-mounted device to terminate the current call hold state.

[0036] In step 102, the third-party control system can monitor in real time the information displayed on the human-machine interface unit that the vehicle-mounted device is in a call holding state, and obtain the call holding time accordingly. The call information is the call holding time. After obtaining the call holding time, since too long a call holding may cause a delay in departure, thereby affecting the overall transportation efficiency, it is possible to determine whether to interrupt the call holding only based on the call holding time. In addition, it is also possible to determine whether to interrupt the call holding in advance in combination with the network signal strength information. Because in the case of poor network signals, the probability of the vehicle-mounted device successfully calling the wireless network device is extremely low, so in this case, interrupting the call holding in advance helps to avoid departure delays.

[0037] When the condition for interrupting the call hold is met, the third-party control system may send an instruction to interrupt the current call hold to the human-machine interface unit in step 103. After receiving the instruction, the human-machine interface unit will request the vehicle-mounted device to interrupt the current call hold state.

[0038] 104. After interrupting the current call holding state, use the specified control method to re-control the door system of the train.

[0039] It should be noted that the onboard device can interrupt the current call holding state directly or call the wireless network device again after the interruption. Therefore, the specified control method in this step can be to call the wireless network device again to send a command to control the opening and closing of the platform door to the station after the call is successful, and control the opening and closing of the car door at the same time to complete the linkage control of the train door system; or the driver can request the dispatcher to control the opening and closing of the platform door and manually control the opening and closing of the car door at the same time to complete the linkage control of the train door system.

[0040] In addition, the human-machine interface unit in the embodiment of the present invention also has a manual wireless connection function. In the case of failure of the third-party system, the driver can actively intervene in the wireless connection function to interrupt the current call holding state.

[0041] It can be seen from this that the train door system control method during the on-site return operation in the embodiment of the present invention not only avoids the possibility of departure delay by interrupting call holding, but also provides an opportunity to call again, thereby increasing the probability of a successful call.

[0042] Based on the above Figure 1 It can be seen from the implementation method that the present invention provides a method for controlling the train door system during the on-site return operation. When the on-board device is in the call holding stage, the call holding state can be actively interrupted to prevent passengers from being stranded or the departure from being delayed due to long-term call holding when the train operation interval is close. Doing so can effectively avoid the adverse impact on the efficiency of railway transportation and ensure that the travel experience of passengers is not damaged. Specifically: First, the call information when the on-board device calls the wireless network device is obtained. Then, it is determined whether the conditions for interrupting the call holding are met according to the call information. Once the conditions are met, an instruction to interrupt the current call holding will be issued to the human-machine interface unit. After receiving the instruction, the human-machine interface unit will issue a request to the on-board device to interrupt the current call holding state. Once the call holding state is interrupted, the specified control method will be used to re-operate the train door system. In this way, there is no need to wait for the call holding state, and the control of the train door system can be quickly restored, which helps to improve the overall operating efficiency and the travel experience of passengers.

[0043] Furthermore, as a Figure 1 The embodiment shown in the figure is refined and expanded. The embodiment of the present invention also provides another method for controlling the train door system during the on-site return operation, such as Figure 2 As shown, the specific steps are as follows:

[0044] 201. Obtain call information when the vehicle-mounted device calls the wireless network device.

[0045] Among them, the implementation method of step 201 is the same as that of step 101, and can achieve the same technical effect and solve the same technical problem, and will not be repeated here.

[0046] 202. Obtain call holding duration in the call information and network strength change information within a preset time period.

[0047] 203. Determine whether a condition for interrupting the call hold is met according to the call hold duration and the network strength change information within a preset time period.

[0048] In step 202 to step 203, the signal strength (RSSI, Received Signal Strength Indication) of the wireless network device can be monitored in real time through a dedicated communication device; or the network signal strength can be monitored in real time from a wireless access point (AP) using a standard protocol such as the Simple Network Management Protocol (SNMP); in addition, it can also be checked whether information such as the network signal strength is displayed on the human-machine interface unit. If so, the wireless network signal strength information displayed in real time on the human-machine interface unit can be directly monitored in real time. By monitoring the network signal strength of the wireless network device, the network strength change information in the recent period (preset time period) can be counted.

[0049] In this embodiment, when the vehicle-mounted device is in the call holding stage, it is possible to monitor in real time whether the call holding duration has reached a preset duration threshold. If the preset duration threshold is reached, it is determined that the conditions for interrupting the call holding are met; on the contrary, if the preset duration threshold is not reached, the network strength change in the network strength change information can be monitored in real time to determine whether the network signal strength continues to drop to the preset minimum threshold. If the network signal strength continues to drop to the preset minimum threshold, it is determined that the network signal strength is too low, and there is a risk that the vehicle-mounted device cannot successfully establish a connection with the wireless network device, so you can choose to interrupt the call holding in advance to avoid wasting time. If the network signal strength does not continue to drop, the current call holding state can be maintained until the call holding duration reaches the preset duration threshold.

[0050] Among them, the start time of the preset time period can be one day ago or one hour ago, etc., and the specific time is not limited; the end time of the preset time period is also not restricted, it can be the time point when it is determined that the call holding needs to be interrupted in advance, or it can be when the call holding time reaches the preset time threshold.

[0051] Among them, the preset time threshold is the optimal value obtained based on statistical analysis of historical data to ensure that it will not affect the departure time of the train.

[0052] If the condition is met, step 204 is executed; if not, wait until the condition is met.

[0053] 204. If the conditions are met, an instruction to interrupt the current call hold is sent to the human-machine interface unit, so that after receiving the instruction to interrupt the current call hold, the human-machine interface unit requests the vehicle-mounted device to interrupt the current call hold state.

[0054] Among them, the implementation method of step 204 is the same as that of step 103, and can achieve the same technical effect and solve the same technical problem, and will not be repeated here.

[0055] 205. After interrupting the current call holding state, use the specified control method to re-control the door system of the train.

[0056] In this embodiment, when deciding which designated control method to use to re-control the door system of the train, the current network signal strength can be obtained first, and then the success probability of the on-board device re-calling the wireless network device can be determined based on the current network signal strength, and then the door system of the train can be re-controlled based on the success probability.

[0057] Specifically, it can be determined whether the success probability has reached a preset probability. If the success probability has reached the preset probability, the on-board device can be controlled to call the wireless network device again. This process is manifested in that the execution subject of the present invention sends an instruction to the human-machine interface device to request the on-board device to call again when the success probability reaches the preset probability. After receiving the instruction, the human-machine interface device sends a wireless network connection request to the on-board device. The on-board device responds to this instruction and initiates the network connection again. At this time, if the wireless network device successfully responds to the connection request of the on-board device and feeds back a successful connection message, the call is deemed to be successful, and a success prompt is sent to the human-machine interface unit so that the driver can manually confirm the platform end change according to the success prompt. After manually confirming the platform end change, the wireless instruction successfully controls the opening and closing of the platform door and manually controls the opening and closing of the door to complete the control of the train door system.

[0058] Of course, if the success probability does not reach the preset probability, if the on-board device calls the wireless network device again, it is highly likely that the connection will not be successfully established. Therefore, a failure prompt can be directly sent to the human-machine interface unit so that the driver can manually confirm the platform switch according to the failure prompt. After manually confirming the platform switch, the dispatcher is requested to control the platform door switch and manually control the door switch to complete the control of the train door system.

[0059] Furthermore, when judging the success probability of the vehicle-mounted device when re-calling the wireless network device based on the current network signal strength, it is possible to first obtain the correspondence between the preset network signal strength and the success probability, and then match the current network signal strength with the correspondence to obtain the success probability of the vehicle-mounted device when re-calling the wireless network device under the current network signal strength.

[0060] Specifically, the corresponding relationship between network signal strength and success probability can be obtained by the following steps:

[0061] A quantum random number generator is used to generate multiple random numbers, and multiple simulated signal strengths are obtained based on the multiple random numbers. Under each simulated signal strength, the calling situation when the vehicle-mounted device calls the wireless network device again is simulated, and the calling situation corresponding to each simulated signal strength is statistically analyzed to obtain the corresponding relationship between the network signal strength and the success probability.

[0062] When implementing the above steps:

[0063] First: You can first select a suitable quantum random number generation device or call the relevant quantum random number generation service interface to ensure that it can stably output high-quality random numbers to meet the diverse needs of subsequent simulation scenarios.

[0064] Second: the quantum random number generator can be initialized and configured, including setting the output range and format of the random number as needed. For example, the output range can be set to a numerical range suitable for representing the network signal strength (such as -100dBm to -30dBm, where the larger the value, the stronger the signal strength).

[0065] Third: The number of simulations to be performed can be determined based on actual needs and computing resources. Generally speaking, the more simulations are performed, the closer the results are to the actual situation, but the computing cost and time will also increase. Based on this, a small-scale test simulation can be performed first, and then the number of simulations can be gradually adjusted based on the stability and accuracy requirements of the results.

[0066] Fourth: The range and step size of other related parameters can be clarified. In addition to the network signal strength range, other factors may need to be considered, such as the time interval between simulated calls, the duration of each call, etc. The setting of these parameters will also affect the accuracy and reliability of the simulation results, and they need to be reasonably selected according to the actual wireless network communication characteristics and the working mode of the vehicle-mounted equipment.

[0067] Fifth: A quantum random number generator can be used to generate N random numbers. For each random number, it is mapped to a corresponding simulated signal strength value according to a pre-set conversion rule. For example, if the range of the random number is [0,1], it can be converted to a numerical interval of network signal strength through linear mapping or other suitable functions. The generated simulated signal strength value can then be stored in an array or data structure for subsequent call simulation and statistical analysis.

[0068] Sixth: For each simulated signal strength, create a simulation environment to simulate the process of the vehicle-mounted device calling the wireless network device again. This simulation environment can be a software simulation program or simulation platform that can simulate the communication protocol, signal transmission characteristics of the wireless network device and the calling behavior of the vehicle-mounted device. (The platform can be embedded in the execution subject of the present invention or can be independent of the execution subject of the present invention, as long as it can communicate with the execution subject of the present invention)

[0069] Seventh: In the simulation environment, perform call simulation of the vehicle-mounted device according to the set simulation signal strength and other related parameters. Record the results of each call, including whether the wireless network device is successfully connected, the call delay time, data transmission rate and other related information. These results can be saved by setting a flag or recording a log.

[0070] Eighth: Repeat the above call simulation process until each simulated signal strength is simulated a sufficient number of times (for example, each signal strength is simulated N times, where N can be adjusted according to statistical accuracy requirements and computing resources).

[0071] Ninth: All the call results obtained by simulation can be classified and sorted according to the simulated signal strength. For each simulated signal strength, the corresponding N call results are aggregated together to form a data set.

[0072] Tenth: The call results in each data set can be further analyzed and processed. For example, the proportion of each successful call is calculated, that is, the number of successful calls divided by the total number of calls, as the success probability under the simulated signal strength.

[0073] Eleventh: The success probability under each simulated signal strength can be statistically analyzed to obtain a more accurate estimate of the success probability. Statistics such as the mean, median, and standard deviation can be calculated to describe the distribution and stability of the success probability under that signal strength.

[0074] Through the above specific implementation methods, the quantum random number generator can be used to systematically obtain the corresponding relationship between network signal strength and success probability, providing valuable reference for related applications such as train door system control. However, it should be noted that in actual applications, more practical factors and engineering experience are needed to further verify and optimize the results.

[0075] Exemplarily, the corresponding relationship is expressed as follows:

[0076] When the network signal strength is -70dBm, the success probability is 90%;

[0077] When the signal strength is -80dBm, the success probability is 70%;

[0078] When the signal strength is -90dBm, the success probability is 30%;

[0079] When the signal strength is -100dBm, the success probability is 10%.

[0080] The preset probability in the embodiment of the present invention may be 70%.

[0081] Furthermore, as a response to the above Figure 1 In order to realize the method shown in the figure, the embodiment of the present invention also provides a train door system control device for on-site return operation, which is used to Figure 1 The device embodiment corresponds to the aforementioned method embodiment.
